在VDSP中编译uclinux（5）：Milestone-内核启动基本完成

 

经过几天的连续奋战，uclinux for bf561内核基本上启动完成，终于可以休息一下了！看看：

Linux version 2.6.19.3-ADI-2007R1.1-svn ([email protected]) (vdsp 4.5) #2 Tue Sep 25 11:24:43 CST 2007

Serial: Blackfin serial driver

No filesystem could mount root, tried:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

虽然最终panic，但是估计只要在内核的末尾写入一个文件系统做为根系统就可以了（根据setup_arch中的相关提示），或者加载NorFlash / NandFlash的驱动并在上面建立相应的文件系统应该也是可以的。

原来 uclinux 的移植也并非如此高不可攀！大大低于先前估计的难度！
